Abstract: A sluing mechanism driven by one or more electric or hydraulic motors, for excavating or bulk handling machines comprises a pivotable discharger boom mounted on a rotary support or turntable, and a coaxially pivotable superstructure carrying further equipment. The sluing drives of the two coaxially pivotable parts of the machine are connected to each other in such a way that upon pivoting the superstructure, the discharger boom does not follow this pivotal motion. The sluing drive of the discharge boom is designed as a superposed gear and connected to a drive motor for separately sluing the discharger boom. The turntable is provided with a second discharger sluing gear which is driven by a motor having a weaker characteristic than the drive motor or motors for sluing the superstructure. The characteristic of the motor driving the second discharger sluing gear may be adjustable.

Abstract: A bland and nutritive soybean food product is produced by a process involving the steps of heating a proteinaceous soybean material with steam to preferably 220.degree. F. and subjecting the proteinaceous soybean material to lower alcohol vapors. Initially, the soybean material is placed in a closed vessel and the alcohol is added to the soybean material in a preferred weight ratio of approximately 9 pounds alcohol to 60 pounds soybean material along with a small quantity of water. The vessel has agitators that agitate the soybean material sufficiently to "fluidize" the material within the vessel. Steam is injected into the vessel and when the temperature of the soybean material preferably reaches 220.degree. F., the steam is stopped and the proteinaceous soybean material is kept at that temperature in the closed vessel for at least thirty minutes.

Abstract: This disclosure illustrates and describes a liquid packaging machine including a base frame having a vertical keel mounted along the longitudinal centerline thereof. The units relating to forming blanks into cartons, filling the cartons with consumable liquids, and sealing the filled cartons, along with the required conveying means, are all mounted on one side of the keel, while the motor and related drive and indexing mechanisms are mounted on the other side of the keel, operatively connected to the forming, filling, sealing, and conveying means.

Abstract: In a ball and socket joint comprising a ball and a socket in mutual swivelling sliding engagement with each other, the ball having a stud integrally formed at one end thereof and projecting outwardly through one end of the socket, the improvement consisting in forming the socket with an annular groove circularly disposed at the edge of the open end of the socket for fitting and retaining therein the beaded end of a flexible oil-resistant seal having a bellows type body provided at one end with an annular band stretched over the periphery of the stud.

Preferably, the sealing shell is made of two half-shells, for facility of assembly.

Abstract: An in-arm hydropneumatic suspension system includes a road wheel spindle connected to a vehicle hull. A road wheel arm has a spindle housing on one end supported by complementary tapered roller bearings for oscillation on the spindle; the opposite end of the road wheel arm defines an air spring housing for air spring means supporting the sprung mass of the vehicle. Damper components of the suspension unit are located remotely of the air spring at a location in the spindle housing so as to isolate the air spring operation from damper generated heat and wherein damper generated heat is dissipated from crankcase oil in the spindle housing directly to the hull.

Abstract: Provided is a method and apparatus for molding and winding in a continuous operation a string of molded items. The molded items of the string or chain are molded in spaced relationship to one another and are connected by molded scrap connectors. The string of molded items is then advanced until only a trailing connector of the last molded item extends into the mold cavity. Upon subsequent molding operation, therefore, the subsequent molded item is molded integral with the existing string of molded items. The continuous string of molded items is kept under constant tension and wound periodically into a coil. The molding, advancing, tensioning and winding operations are all integrated and synchronized in order to provide a wound package which greatly facilitates its use in an automatic assembly operation.

Abstract: An AC split-phase induction motor has a two-pole run winding, a four-pole run winding and a separate start or phase winding. The two-pole winding is connected directly to a corresponding first power terminal. The second run winding is connected to a second power terminal by a solid state gated run switch having a turn-on gate. The start winding is connected in circuit in series with a solid state gated start switch connected to the first power terminal and having a gate connected to a second power terminal. A centrifugal switch connects the first and second power terminals. The gate of the run switch is connected to the start winding circuit and includes connecting Diac and resistance elements to actuate the run switch only in response to a power connection to the second power terminal and the opening of the centrifugal switch. In operation, the motor always starts with the two-pole run winding and the start winding in the circuit. At switching speed, the start switch disconnects the start winding.

Abstract: A control system for electronic discharge machining includes an automatic relay control and a current cutoff control of particular interest. The automatic relay control controls the energy level of machining pulses as a step function of machining cycle period by cutting in or out resistors in a power circuit through the machining gap. Higher frequency pulses are held to a lower current level to avoid power transistor overload. The relay control circuit includes multivibrators, energized at progressively higher values of pulse period by the counters, and an output circuit for each multivibrator which controls one of the relays which vary the gap circuit resistance. The relay control circuit also includes a threshold responsive circuit which senses any change in the several relay controlling output signals and acts to interrupt machining pulses briefly to allow time for relay operation.
